Plasma Cannon

NIKON Z 7 + NIKKOR Z 14-30mm f/4 S @ 14 mm, 559 sec at f/8, ISO 100

A plasma cannon was our very first shot of our evening session at Middle Head Fort. It’s 9:30PM and a lazy 559 second exposure to start with. This was really just a tester and we’re just working our way into things. Turned out ok tho 🙂

We’re at one of the old wartime cannon emplacements. The circular area looked ideal for some orbs and domes so we obliged

Gerry on the voluminous blue EL wire in the foreground and my 10 colour torch in red mode on the walls. I’m having my first go at the new technique with the LED umbrella for the plasma orb (two colours – red and blue). It worked out well we thought. I was also trying the green auxiliary leds on my new Emisar D4V2 torch. If you look closely you can see some flashes of green in there in the middle. Alas the lines are not bright, solid or distinct enough. Thus the aux leds are not really viable for this light painting. Perhaps with much slower motion, pointed directly at camera at a higher exposure (say f/5.6 @ ISO 400) it might work when mixed with other weaker light sources

Note: These photographs (especially the wider shots) look much better when larger. To see larger versions in an inline overlay slideshow gallery viewer click any of the images.
